UNITED STATES ATENT ARTHUR H. FOWLER, OF BUFFALO, NElV YORK.

SECTIONAL BOILER.

SPECIFICATION forming part Of Letters Patent NO. 425,415, dated April 15, 1890.

Application filed May 25, 1888. Serial No. 7 (NO modem To all whom it may concern.-

Be it known that I, ARTHUR H. FOWLER, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Sectional Boilers, of which the following is a specification.

My invention relates to improvements in sectional hot-water or steam boilers for heating buildings or for other purposes, and will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which-'- Figure 1 is a front sectional elevation. Fig. 2 is a vertical longitudinal central section.

- Fig. 3 is a top plan view, the elbow at the back (shown in Fig. 2) being removed. Fig. 4 is a horizontal section through a boiler on line a. b, Fig.2, all portions below the section being omitted. Fig. 5 is a horizontal section through the boiler on line d, Fig. 2, omitting all portions below the section.

This boiler is made up of a series of sections, either more or less than the number shown in the drawings. In said drawings, in which a suitable nu mbcr of sections are shown, 1 represents the top section. It is provided with the smoke-chamber 2, (shown in Fig. 2,) the water-chamber 3, and on each side is an inclined recess a, leading down into the fuelmagazine, one of which is shown in the sectional side of Fig. 1. At the back of the top section is an opening 5, (shown in Fig. 3,) leading into the descending smoke-flue e, and is provided with a removable cover 6. (Shown in Fig. 2.) The next section 7, below the top section 1, is provided with openings f on each ide leading into and forming a portion of the 1; rel-magazines 8, each of which is provided w, "th removable covers 9, one of which is shr wn in Fig. 1,and with an opening forming a t of the descending smoke-flue; also cross wat r-tubes. This section 7 is also provided with a water-chamber 10, which surrounds the li'v o magazine-chambers (see Fig. and

the en ire body of the furnace. The waterhamb r also surroundsthe descendingsmokeflue e at the point 12 and passes through the curved tubes 13. The object in making the 1 tubes 13 f a curved or slightly-bent form, as shown, is 1.0 avoid the danger of breaking by the expansion or contraction of the metal.

The sections 14, below section 7, are all of substantially the same form, having the same water-space and the curved water-tubes 13. 8

Sections 7 and 1% are each provided with a removable screw-plug 15, (see Fig. 2,) having a wrench-section 16, by which they are readily putin or takenout by means of awrench. Their object is to provide the means for getting at the interior of the sections to clean them out when required. Below the section 14 is a section 17, having inclined sides 18, (see Fig. 1,) terminating in openings communicating with the fire-chamber. The sides 18 incline from both ways in toward the center of the combustionchamber 20, (shown in Figs. 1 and 2,) their object being to cause the fuel to flow into the furnace so as to lay in an inclined position, substantially as shown in dotted lines 21, Fig. 1, inclining both ways from each fuel-magazine, the object being to so arrange the fuel within the furnace that it will present a large surface for the combustion of the gases. In this section is also a water-space 22, which partly surrounds the section and entirely surrounds the descending sinoke-flue e and all of the combustion-chamber except the opening 23 for the door 24:. (See Fig. 2.) The section 25, below the section 17, forms the lower portion of the fire-chamber, and has a waterchamber 25 entirely surrounding it and also surrounding the descending smoke-flue e. In this section is pivoted by pivots 26 the inclined side grate-pieces 27, one on each side of the furnace directly opposite each other, only one of which is shown in Figs. 1 and 2. Both are exactly alike. 28 represents arocking or turning grate located between the inclined side pieces 27. The base 29 is provided with an elbow 30 to receive the pipe; also, an ashchamber 31 and the usual door These bOllGPSGGhlODS are all provided on their upper sides with an upwardly-projecting rim 33, into which the lower edge of the adjoining section fits, and each section is provided with outwardly-proj ectin g cars 34:, (shown in Figs. 1, 3, at, and 5,) by which they are secured together by bolts (See Fig. 1.) Each section is provided with openings 36, through which the water and steam pass from one to the other. Each section with the several parts and crosstubes 13 are all preferably cast in one piece; but, if desired, the tubes maybe put in separately in any well-known way. The sections are also provided with openings 40, (see Figs. 1, 2,) by which the exterior of the cross watertubes may be conveniently reached and cleaned.

In operating with the boiler the heat and products of combustion pass up among the water-tubes into the chamber 2, and from thence into and down through the descending smoke-flue e and through the elbow into the outlet-pipe.

I claim as my invention 1. Ina sectional steam-boiler, two vertical fuel-magazines located at opposite sides of the boiler, facing each other, and having inclined bottoms leading into the fire-chamber, the whole inclosed within a boiler or case forming an entirely-surrounding water-cha mber around the bottom and sides of the same, substantially as described.

2. A sectional boiler consisting of a series of sections provided with curved cross watersections, openings forming a portion of two fuel-reservoirs, an opening forming a part of the descending smoke-flue, openings forming a water or steam communication between the sections when put together, and lugs or ears by which the sections are bolted together, in combination with top and bottom sections, the upper section forming the top of the boiler having a top water-chamber, a surthe combustion-chamber, and water-surronnded descending smoke-flue, the Whole formed of sections put together substantially as described.

4. A sectional steam-boiler section consisting of the outer sides, top, and bottom inclosing a water-chamber, a large opening through the center, having a series of cross water-tubes, an opening through the section forming a portion of the descending smokeflue, an opening through the section at two opposite sides forming portions of the fuelmagazines, openings through the sides for forming water or steam communication from one section to another, and lugs by which the sections are secured, substantially as described.
